Knowledge about torpor in free-ranging subtropical bats is scarce and it is widely believed that low and stable ambient temperatures are necessary for prolonged torpor. We present temperature-telemetry data from free-ranging male (n = 4) and female (n = 4) subtropical vespertilionid bats, Nyctophilus bifax (~10 g), exposed to pronounced daily fluctuations of ambient temperature. All bats used torpor on every day in winter and both males and females exhibited multi-day torpor bouts of up to 5.4… 

Opportunistic hibernation by a free-ranging marsupial

Examination of torpor patterns in the free-ranging western pygmy-possum shows that torpor use in C. concinnus is strongly influenced by small-scale microclimatic conditions, and the first quantitative data on a marsupial species expressing opportunistic hibernation during winter in the wild is presented.

Fat and fed: frequent use of summer torpor in a subtropical bat

It is provided the first evidence that use of torpor in a free-ranging subtropical mammal is positively related with high body condition index, suggesting that employment of torpora is maximised and foraging minimised not because of food shortages or low energy stores but likely to avoid predation when bats are not required to feed.

Comparison of Variables of Torpor Between Populations of a Hibernating Subtropical/Tropical Bat at Different Latitudes

The differences found in variables of torpor in free-ranging Nyctophilus bifax during winter from a subtropical region and a tropical region suggest that populations of heterothermic mammals can adapt or acclimatize to the local climate of the habitat that they occupy, even when thermal conditions are mild.

Does torpor of elephant shrews differ from that of other heterothermic mammals?

Time required for the reduction of Tb to a Tb − Ta differential was faster for >1-day torpor bouts than those lasting ≤1 day, suggesting that the duration of a bout might be determined at the beginning, not during, a bout.

Seasonality of torpor patterns and physiological variables of a free-ranging subtropical bat

It is shown that torpor is used regularly throughout the year in a free-ranging subtropical bat and the first evidence demonstrating that torpora patterns and thermal physiology change with season is provided.

Do season and distribution affect thermal energetics of a hibernating bat endemic to the tropics and subtropics?

Thermal energetics of N. bifax do not vary seasonally and in many aspects are similar in tropical and subtropical bats; however, torpid individuals from the subtropics allow body temperature to fall to significantly lower values than those from the tropics.

Some like it cold: summer torpor by freetail bats in the Australian arid zone

It is demonstrated that this desert bat uses torpor extensively in summer and often rewarms passively from torpor to maximise energy and water conservation.

Thermal biology and roost selection of free-ranging male little forest bats, Vespadelus vulturnus, during winter

Insectivorous bats are particularly susceptible to heat loss due to their relatively large surface area to volume ratio. Therefore, to maintain a high normothermic body temperature, bats require

Torpor use by Free-ranging Pallid Bats (Antrozous pallidus) at the Northern Extent of Their Range

Torpor duration increased as mean daytime Ta decreased albeit the relationship differed between individuals and there was no significant effect of individual on the relationship between minimum Tskin during torpor and Ta.

Torpor, arousal and activity of hibernating Greater Horseshoe Bats (Rhinolophus ferrumequinum)

Patterns of torpor and subsequent activity are consistent with predictions that torpor lasts until a critical metabolic or water imbalance is achieved, and because metabolism and water loss are temperature-dependent, torpor bout duration decreases with increasing temperature.

Thermoregulation in two free-ranging subtropical insectivorous bat species: Scotophilus species (Vespertilionidae)

Despite physical differences between roosts, foliage and building roosting appeared equally thermally labile, resulting in torpor bouts of similar depth and duration between in free-ranging subtropical bats.

Torpor and activity patterns in free-ranging sugar gliders Petaurus breviceps (Marsupialia)

It is shown that cold or wet conditions curtail foraging in wild sugar gliders and that they employ daily torpor regularly during adverse weather, which suggests that minimisation of energy loss by the use of torpor in sugar glider is pivotal for their survival in the wild.

Hibernation by tree-roosting bats

This study provides further evidence that models of torpor patterns and energy expenditure from hibernators in cold temperate climates are not directly applicable in milder climates, where prolonged torpor can be interspersed with more frequent arousals and occasional foraging.

PHYSIOLOGICAL TRAITS AFFECTING THE DISTRIBUTION AND WINTERING STRATEGY OF THE BAT TADARIDA TENIOTIS

The hypothesis that Tadarida teniotis, the molossid species reaching the highest latitude worldwide (46° N), lacks the extreme physiological adaptations to cold that enable other sympatric bats to enter further into the temperate zone is tested.

Torpor, thermal biology, and energetics in Australian long-eared bats (Nyctophilus)

The study suggests that Australian Nyctophilus bats have a low basal metabolic rate and that their patterns of torpor are similar to those measured in bats from the northern hemisphere.

Results indicate that M. condylurus maintained an optimally small Tb–Ta differential by readily becoming torpid under roosting conditions, thereby minimizing energy expenditure.

Why Do Brown Long-eared Bats (Plecotus auritus) Fly in Winter?

It is suggested that typically in P. auritus winter flights, many days pass without a winter flight, which is not induced by the onset of starvation (and hence the need to feed) or byThe onset of dehydration ( and hence the needs to drink).
